One thing I'm interested, is if there will be a portion of the maze underneath Paris, within the Catacombs.
That'd actually make sense, as there are plenty of scaring opportunities that could come out of the catacombs of Paris.
Edit: Thinking about it more, I could even see them do something that'd connect Dead Exposure to Black Death Rising from 20 Year's of Fear, similar to how Body Collectors: Collections of The Past was a crossover between BC and Shadybrook.
